Wax compositions may be obtained by providing an olefinic feed comprising a first linear alpha olefin having m carbon atoms and a second linear alpha olefin having n carbon atoms, wherein m and n are independently selected integers each ranging from about 12 to about 100, and the olefinic feed optionally comprises one or more internal olefins and/or one or more branched olefins; contacting the olefinic feed with a metal carbene catalyst in a reactor; forming ethylene and a hydrocarbon substance comprising a linear olefin dimer comprising two carbon atoms less than a sum of m and n; removing the ethylene from the reactor while forming the linear olefin dimer; and isolating a wax composition comprising the linear olefin dimer, a hydrogenated reaction product thereof, or any combination thereof.

Wax compositions comprising linear olefin dimers or hydrogenated variants thereof and methods for production thereof

A supported catalyst system is based on a transition metal carbene including the moiety M1=CR*), wherein Mis the transition metal and R* is hydrogen or a C-Chydrocarbyl. The catalyst system can be supported on a metal oxide support such as silica or the catalyst can be self-supporting. Methods of making the catalyst system can involve precursors based on and/or reacted with aluminum alkyls, halides, and/or alkoxides. Methods of polymerizing cyclic olefins with the catalyst system can obtain polyalkenamers, cyclic olefin polymers, cyclic olefin copolymers, and other metathesis reaction products. The supported catalyst and/or monomer can be recovered and recycled to the polymerization reactor.
